Admissible evidence, which was found insufficient to prove the commission adultery on a certain day, is not thereby rendered incompetent in the trial of a subsequent libel for divorce to prove the offence on another day. A decree in a divorce proceeding, adverse to an allegation of adultery committed on a certain day and on divers other days, is not necessarily an adjudication covering the whole time alleged. On. the trial of a like allegation in a subsequent libel, evidence of the issue actually tried in the former case may be admissible.
